Application-filed July 27, 1914'. Serial No. 853,325.

Kalamazoo, Michigan, have invented certain new and useful Improvements in'Brooders, of which the following is a specification.

This invention relates to-improvementsin brooders.

The main objects of this invention are: First, to provide an improved brooder in which rapid and even circulation of air is maintained through the brooding chamber andone in which the incoming airls-effectively warmed and distributed within the breeding chamber.

Second, to provide an improved brooder in which the air has a free circulation within the brooding chamber, hovers and'other obstructions being eliminated.

Third, to provide an improved brooder having a circular brooding chamber in which the heated air is delivered dow-nwardlyand centrally Within the brooding chamber thereby effectively overcomingthetendency ofthe chicks to pile up or crowd against a wall.

Fourth, to provlde an lmproved brooder- 1n which an efi ectlve circulation of air 1s ma1n ta-ined through a brooding chamber provided with entrance and eX1t doors perinittingfree entrance and=exit of-the chicks without i11- terferingwith the normal clrculation of "air within the brooding chamber.

Fifth, to provide in a brooder an improved" entrance and exit door structure inwhich the doors automatlcally close and may be operated by very young chicks.

Sixth, to provide animproved brooder which is comparatively simple andeconomicontrol:

Further objects, and objects relating to cal in structure and=very easy to regulate or;

structural details, will definitelyappear from thedetailed description to follow.

I accomplish the objects of my invention" by the devices and means describedin' the following specification. The invention is clearly defined and pointed out in theclaims.

A structure which is a preferred embodi ment of my inventlon is clearly lllUStTZI/DGCI in the accompanylng drawing form nga part of this specification, in which:

FigureI 1s a plan v1ew 0f=a brooder embodying the features of my HIVBHi/IOIL r 'EigrIIis aside-elevation thereoifthe lampofFig; If, the thermometer, thermostat and lamp being shown in full lines, the lamp housing being omitted.

Fig. is a vertical section on a line corresponding to line H ofFig. I.

Fig. V is a detail vertical section through the GXltOIl' a line corresponding to line 55 of'Fig. IV. a

Fig. VI is a horizontal section 011 a line corresponding to line 6-6 of Fig. IV.

Fig. VI I is adetail view partially in vertical: section on a line corresponding to line 77 of Fig. I, showing-the 'arrangement of the discharge flue of the heating drum.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking-in the direction of the little arrows at the ends of the section lines;

Referring-to the drawing, the structure illustrated consists of an outer cylindrical sheet metal casing 1 comprising side and'top walls: and an inner cylindrical sheet metal casing 2 also comprising side and top walls; The'casingsare of such relative size that when the innercasing is arranged within the outer there is a space between the top walls and an annular space between the side walls.

Vertical partition strips 3 betweenthe side walls-to dividethe-space between thewalls into substantially equal spaces providing a pairof opposed air inlet passages 4: and a pair of opposed ainclis charge passages 5. Partition strips 6 are arranged between thetop walls to provide a connecting passage 7 for the discharge passages 5. The top wall of the outer casing isprovidedwith a discharge flue 6 for the discharge passages. The outercasingis proa vided with a-series of air inlet openings 9 near its bottom foreaclr inlet passage, while the lnner casing 1s provided with aseries of dellvery openings 10 near 1ts upper end throu hwhich the air asses from at inlet b a i n passages into the'inner caslng: The 1111161 posed in a spaced relation to the top ofi the are arranged in the brooding chamber, and, as its struc-- inner casing and below the air delivery.

which does not interfere with the circulation openings 11 so that the incoming air passes across the top of the drum and down through the central opening 13 thereofand is delivered centrally into the brooding chamber below the drum.

The lamp housing 14: for the lamp 15 is mounted at one side of the outer casing and is provided with a flue 16 delivering to the drum through the walls of the inner and outer casing and with an escape flue 17 The escape flue is provided with a damper 18 which is controlled by the thermostat 19 connected by a suitable lever mechanism, designated generally by the numeral 20, to the damper. The thermostat is arranged withtural details form no part of my present invention, I do not further describethe same herein.

The heating drum is provided with a discharge flue 21. This flue is arranged adjacent to the lamp flue 16, apartition plate 29: being interposed between the lamp fine and the discharge flue of the drum so that the heated air and gases must circulate around the heating drum.

I preferably provide a thermometer 25 which is suspended centrally within the brooding chamber from the closure 24: provided for a central opening in the top of the inner casing through which the thermometer may be introduced and removed. This closure and the attached thermometer :is adapted to be removed through the flue 8.

fWith the parts thus arranged the air passes through the inlet openings 9 and air passages l and is delivered through the openings 10 into the inner casing above the drum across WlllCh 1t passes and 1s dellvered This arrangement of parts insures a rapid and constant circulation within the brooding ohamberand foul air is continually drawn from the brooding chamber and heated air delivered thereto. H

By providing the circularbrooding chamber and delivering air centrally thereto I find that-in use the chicks cluster or group, themselves at the center of the brooding chamber in the path of the warm air and that there is no tendency forthcm to crowd or pile against thewalls, which is likely to cause loss by smothering or injuryto the chicks. a i f To provide a means of entrance and exit within the brooding chamber and one which even very young chicks soon accustom themselves to using so that they pass freely to and from the brooding chamber I provide an outwardly projecting passage member 25 which is mounted in a suitable opening in the outer casing to project therefrom and which is provided with a vertical longitudinal partition 26 providing an entrance passage 27 and an exit passage 28. Partitions 29 are interposed between the inner and'outer casings to close the inner casing from the air inlet passage 4;.

Entrance and exit doors 30 ndBl respectively are preferably formed ofmica or other light transparent material so that the chicks can see through the same and at the same time the doors can be readily lifted by the chicks.

The doors are provided with jamb frames door is arranged at the inner end of the entrance passage, while the exit door is arranged at the outer end of theexlt passage,

the entrancedoor being inclined outwardly while the exit door is inclined inwardly.

I The doors are preferably arranged so that their lower ends overlap the ends of the bottoms ofthe passages, as shown. -This prevents a. chick getting a foothold within the passage and standing in front of the door so as to prevent another chick opening thesame. The fact that poultry will keep away from an inclined surface is well known I by experienced poultry raisers.

.It is found in practice that even very young chicks will enter thepassages and push the doors open and that they soon become accustomed to the same so that they pass freely to and from the brooding chamher; i

By this arrangement of doors the passages cannot become blocked by chicks collecting on the side towardwhich the doors swing so. that the doors remain, unobstructed.

Further, the doors automatically close sothat the circulation within the brooding chamber is not interfered withor materially affected by the opening and closing of the doors. V

I have illustratedand describedmy improved brooder in detail in a'form in which I have embodiedthe same and, found highly Y satisfactory in practical use. I have not attempted to. lllustrate' V or describe. various modifications which I contemplate as possi ble as I believe the disclosure made will en- 7 able those skilled in the art to which myinvention relates to embody or adaptjthe same i as conditions may render desirable.
